Squash Ball Investigation

        In my investigation I am going to see whether or not the temperature of a squash ball affects the height it bounces to.

Variables

Temperature of squash ball

Height from which the ball is dropped

I am going to change the temperature of the squash ball. I will measure the height that the ball bounces to when dropped from a certain height. I think that the hotter the squash ball is the higher it will bounce. This will happen because when rubber is heated it becomes softer and because the ball is softer it will bounce higher because it is easier to squash. It will bounce higher because the more squashed the ball gets when it is dropped, the more pressure it created inside the ball, therefore when the potential energy is transferred into kinetic energy the ball will bounce higher.

Method

  1. Set up the apparatus as shown in the diagram above.
  2. The first temperature we will use is room temperature because we do not need to heat the ball.
  3. Hold the ball at the top of the metre ruler.
  4. Make sure that your partner is looking at the ruler from eye level so that they can see where the ball reaches when it bounces.
  5. Drop the ball from the top ...
